Answer:

7x-1

Step-by-step explanation:

14 + 7x - 15 = k

7x - 1 = k

Finding x,

14 + 7x - 15 = k

=> 14 + 7x = k + 15

=> 7x = k + 15 - 14

=> x = (k + 1)/7

So, 7 * (k+1)/7 - 1 = k

k + 1 - 1 = k

=> k = k

So the answer is true that 7x - 1

pychu [463]

y  intercept = 1/2

<u>Step-by-step explanation:</u>

Step 1:

Formula y=mx+b in Slope Intercept form( whereas m= slope of the given equation, b= y intercept)

Step 2:

Comparing the given equation y = -3x + 1/2

Find the equation of the line that is perpendicular to y = - 1/3 x + 2 and passes though the point (-5,2)
elena55 [62]

Answer:

y - 2 = 3(x + 5)

Step-by-step explanation:

The given equation has slope -1/3.  Any line perpendicular to the given line has a slope which is the negative reciprocal of -1/3, which comes out to +3.

Use the point-slope formula y - k = m(x - h):

y - 2 = 3(x + 5)

The same Honey is sold in two different size jars. Large jar= 540g for £4.10 Small jar= 360g for £2.81. By considering the amoun
Ray Of Light [21]

Answer:

From our calculations the large jar is the best value for money because a penny buys more honey

Step-by-step explanation:

<h2>In this problem we are expected to determine which purchase of honey is the cheapest ? large jar or small jar ?.</h2><h2 />

We will determine which has the best value for money using the quantity a pound can purchase.  

firstly for the large jar.

if £4.10 will purchase 540g of honey then,

   £1.00 will purchase xg

cross multiplying to find x will have

x=  \frac{1.00*540g}{4.10}

x= 131.7grams

Hence for the large jar a penny would buy 131.7g of honey

secondly for the small jar

if £2.81 will purchase 360g of honey then,

   £1.00 will purchase xg

cross multiplying to find x will have

x=\frac{1.00*360g}{2.81}\\x= 128.1gram

Hence for the small jar a penny would buy 128.1g of honey
